This chapter talked about the different frameworks and programming models that can be run on YARN. We discussed Apache Samza and Storm on YARN in detail.

With the wide acceptance of YARN in the industry, more and more frameworks will support YARN, taking complete advantage of YARN's generic features.

We looked at the existing frameworks that are integrated with YARN at the moment.

There is a lot more work going on in the industry to make existing and new applications run on YARN.

In Chapter 8, Failures in YARN, we will discuss how faults, failures at various levels, are handled in YARN.
